Physiological and Biochemical Responses in Microalgae , and NCC466 Exposed to High Salinity and Irradiation.

(Chlorophyceae), (Cyanophyceae), and (Bacillariophyceae) were isolated from three ponds in the solar saltern of Sfax (Tunisia). Growth, pigment contents, and photosynthetic and antioxidant enzyme activities were measured under controlled conditions of three light levels (300, 500, and 1000 µmol photons m s) and three NaCl concentrations (40, 80, and 140 g L). The highest salinity reduced the growth of and NCC466 and strongly inhibited that of .

The Effect of Colored and White Light on Growth and Phycobiliproteins, Chlorophyll and Carotenoids Content of the Marine Cyanobacteria sp. and sp. in Batch Cultures.

Two local marine cyanobacteria, sp. and sp., were batch-cultured under 18-19.

Changes of bacterioplankton apparent species richness in two ornamental fish aquaria.

We analysed the 16S rRNA gene diversity within the bacterioplankton community in the water column of the ornamental fish Pterophyllum scalare and Archocentrus nigrofasciatus aquaria during a 60-day growth experiment in order to detect any dominant bacterial species and their possible association with the rearing organisms. The basic physical and chemical parameters remained stable but the bacterial community at 0, 30 and 60 days showed marked differences in bacterial cell abundance and diversity. We found high species richness but no dominant phylotypes were detected.
